Background and Objective: Self-injury (SI), also called self-mutilation or cutting, is highly stigmatized emotional disorder. The aim of this study was to estimate the incidence rate of self-injury among male pupils in Tabriz – North West in Iran and to evaluate the associated risk factors. Materials and Methods: In this longitudinal study of all the pupils high school in Tabriz, 1772 (13.7%) were randomly sampled, and assessed in this and subsequent year. A self-administered questionnaire with 48 questions was distributed to high school in February and March 2005. After one year (February and March 2006), another questionnaire with 10-items was distributed to those students to determine the incidence rate of self-injury. The influence of different factors on self-injury was evaluated with a logistic regression model. Results: The mean age of the subjects was 16.3±0.87 (min 15, max 19) years. At the end of follow–up, 4.8% of pupils reported incidence of self-injury. Most type of incidenced self-injury were cutting and burning. The results of logistic regression model indicate that transition in smoking stages (OR=2.81), incidence of alcohol drinking (OR=2.27) and having smoker friend (OR=1.78) were factors associated with incidence of self-injury. Conclusion: This study showed that incidence rate of self-injury in this group of adolescents was 4.8% in one year, which related to age, alcohol and ciggaret smoking.

Background and Objective: Tinea versicolor is a common fungal infection of the skin caused by the dimorphic lipophilic yeast Pityrosporum orbicular (Malassezia furfur). Lesions begin as multiple small, circular macules of various colors. The upper trunk is most commonly affected due to the side effects of oral treatment and drug resistance, this study was done to compare the therapeutic efficacy of topical terbinafine versus topical ketoconazole in Tinea versicolor. Materials and Methods: This Randomized double blind clinical trial study was conducted between 2008-09. Sixty nine patients with a clinical diagnosis of pityriasis versicolor confirmed by microscopic potassium hydroxide (KOH) examination were taken for the study. Patients randomly divided into 2 treatment groups: 35 patients in terbinafine group, treated by terbinafine 1% once daily for 2 weeks and 34 patients in ketoconazole group, treated with ketoconazole 2% once daily for 2 weeks. Five patients of terbinafine and 4 patients of ketoconazole groups were excluded due to lack of follow-up. Patients were followed up at monthly intervals for 3 months and recurrence and cure rate for each subject were recorded. Data was analyzed by SPSS-16, t student and Chi-Square test. Results: The mean moderate cure rate obtained one month after treatment was 20% in terbinafine group versus 3.3% in ketoconazole group, and there was no any significant difference between two groups. The mean moderate cure rate two month after treatment was 67.7% in terbinafine group and 60% in ketoconazole group (P<0.05). The mean complete cure rate three month after treatment was 73.3% in terbinafine group and 10% in ketoconazole group (P<0.05). The percent of positive KOH examination, three month after treatment was 10% in terbinafine group and 36.7% in ketoconazole group (P<0.05). Conclusion: This study showed that terbinafin is more effective than ketoconazole in treatment of tinea versicolor.

Background and Objective: Several strains of the Echinococcus granulosus have been described based on morphological characters, intermediate host specificity and/or genetic analysis of mitochondrial and nuclear DNA. The aim of this study was to characterize different E.granulosus isolates by using sequences of mitochondrial atp6 gene.

Materials and Methods: In this study, Sixty infected liver and lungs of cattle, sheep and goats were collected from the abattoir of Varamin city-Iran during 2008. Protoscoleces were removed from each fertile cyst and DNA extracted. New and specific primers were designed for two existing genotypes (G1 and G6) of E. granulosus known to occur in Iran and applied in PCR reactions.

Results: The new primers selectively amplified the G1 and G6 genotypes of E. granulosus with specific bands of 708 and 705 bp respectively. The G1 genotype was identified in all fertile cyst samples.

Conclusion: This study showed that the new primer pairs which specifically amplify portions of the mitochondrial atp6 gene of the G1 and G6 strains of Echinococcus granulosus are proper molecular marker for investigating genetic variation in a number of isolates of E. granulosus from a range of hosts (sheep, goats, cattle) in Iran. The result of sequenced samples showed that our sequences were the same as those reported previously for these strains.

Background and Objective: Breast cancer is one of the most common types of cancer among women. HER-2 molecule as the receptor of tyrosine kinase from the family of epithermal growth factor is a major cause of cancer. The Herceptin protein molecule, which is an anti-HER-2 antibody, can play an important role in the diagnosis and treatment of breast cancer. This study was done to subcloning of Herceptin gene, expression in the prokaryotic system (E.coli) and produce Herceptin recombinant protein for use in the treatment of breast cancer.

Methods: In this descriptive – laboratory study, Herceptin gene from synthesized construct was isolated by enzyme digestion, and then subcloned to the expression vector pET28a. Subcloning of the gene was confirmed using PCR and enzyme digestion. After transferring the vector into E.coli BL21 DE3, expression of the recombinant Herceptin gene was induced by IPTG. The recombinant protein was evaluated by SDS-PAGE and purified with Ni-NTA column chromatography and finally verified by western blotting using anti-histidine antibody. The survival of cells adjacent to recombinant Hercaptin by MTT was investigated.

Results: Following the subcloning of the Herceptin gene, PCR and enzyme digestion, the 741 fragment of the Herceptin gene was confirmed. Confirmation of Herceptin's recombinant protein and its evaluation on SDS-PAGE gel about 27 kDa was done. The recombinant protein was also confirmed with anti-histidine tag. The purified protein adjacent to the SKBR3 cell line was able to block the growth of cancer cells.

Conclusion: Regarding the expersion of HER2 antigen on surface of breast cancer cells, Herceptin can act as antibody blocker and it arrests the growth of breast cancer cells.

Background and Objective: Previous studies have advanced our understanding of the impact of executive functions on eating behavior. Given the considerable evidence of executive dysfunction among obese individuals and the bidirectional relationship between cognition and obesity, it is crucial to include educational components in interventions aimed at enhancing executive functions among obese populations. This study aimed to evaluate the effectiveness of cognitive hypnotherapy in improving executive functions among women with obesity.
Methods: This clinical trial enrolled 30 obese women who were randomly assigned to either an intervention or control group (n=15). The mean ages of the experimental and control groups, respectively, were 40.80±6.02 and 38.47±7.50 years, while their BMIs (kg/m2) were 33.45±3.50 and 33.12±3.47, and hypnotizability scores were 39.67±5.98 and 37.40±7.09. The intervention group received 12 sessions of 2-hour cognitive hypnotherapy. Data collection instruments included the Stanford Hypnosis Susceptibility Scale (1962), Life Experiences, Interests and Values Checklist (1998), and Cognitive Ability Questionnaire (2013).
Results: The results demonstrated that cognitive hypnotherapy significantly improved executive functions (F=7.02, P≤0.01), including inhibitory control and selective attention (F=2.83, P≤0.05), decision making (F=4.13, P≤0.05), planning (F=3.32, P≤0.05), and sustained attention (F=2.83, P≤0.05) in the intervention group.
Conclusion: Given the relationship between cognitive abilities, eating behaviors, and obesity, and the effectiveness of cognitive hypnotherapy in enhancing executive functions, this approach can be used to enhance cognitive functions among individuals with obesity.
